AT RISK
This router has significant issues. Your home network is more exposed than it should be. Anyone on this Wi-Fi (phones, smart TVs, baby monitors, laptops) shares that exposure.
Calix GigaSpire BLAST u6x is a ISP-supplied gateway. The GigaSpire BLAST u6x is manufactured in China.
- Foreign manufacture — FCC ban appliesThe GigaSpire BLAST u6x is manufactured in China. The FCC's March 2026 rule applies to ISP-supplied premises equipment as well as retail routers. Contact your ISP about replacement options.What this means at homeYour home network is more exposed than it should be. Banking sessions, security cameras, and smart home devices all pass through your router.
- ISP controls all configurationCalix GigaSpire devices are fully managed by your ISP. Firmware, configuration, and remote access are all under ISP control. You cannot independently audit the firmware or configure advanced security settings.
- Calix is US-headquartered — no Chinese government legal exposureCalix Inc. is a US public company (NYSE: CALX). The concern here is manufacturing origin under the FCC rule, not corporate jurisdiction.

Here's what closes the gaps.
Your ISP gave you an okay router. You can still have a great network.
Rio Router goes behind your ISP gateway and handles the Wi-Fi side, where the security gaps live. Your ISP keeps your internet connection. Rio gives you a modern, secure Wi-Fi network with all 8 dimensions covered.
Steps to strengthen your home network
1
Contact your ISP to ask about hardware replacement options under the FCC foreign manufacture rule
2
Ask if a US-manufactured or Taiwan-manufactured gateway alternative is available
3
For advanced security control, install a secondary router behind the gateway in bridge/DMZ mode
4
Secure your ISP account with a strong password and 2FA
